AI Technical Summary

Technical Problem

Existing technologies are insufficient to effectively identify and isolate faults such as suspended conductors or high-resistance grounding after a wire break, especially in low-current grounding systems, which can lead to power outages and load losses, affecting power supply reliability.

Method used

By detecting abnormal conditions at the power distribution master station, collecting and uploading line voltage data in real time, determining the fault range using a connectivity matrix, and sending alarm information to maintenance personnel, remote fault location and isolation can be achieved.

Benefits of technology

It improves the accuracy of identifying line breakage faults, reduces the probability of power outages across the entire line, and enhances power supply reliability and fault location efficiency.
